❓ What does oxygen do in human body?

Our body needs oxygen to obtain energy to fuel all our living processes. Carbon dioxide is a waste product of that process. The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells.

How does tetrodotoxin enter the body?

TTX can enter the body by injection, ingestion, inhalation, or via abraded skin. The oral LD50 (i.e. the median lethal dose in test organisms) in mice is 334 μg/kg; in a 75 kg human this would be equivalent to 0.765 mg, thus making TTX 10,000 times more poisonous than cyanide.
